Features May Include:

IMPROVED PRODUCTIVITY AND DURABILITY
The standard poly tine bands provide low friction and a flat surface for smoother crop flow and quieter operation. Additionally, their flexibility and high wear resistance extend the life of the tines, which means less maintenance for you. For even greater durability on the roughest terrain or when quickly baling windrows, heavy-duty gauge wheels are available with your choice of fixed or castering arm designs.

CLEAN AND EFFICIENT PICKUP
Measuring 92.6 inches flare-to-flare and 86.6 inches tine-to-tine, the BigBaler 340 High Density’s 2.35m MaxiSweep™ pickup is perfect for baling wide swaths from today’s high-capacity combines. Solid-steel bar stock tine bars resist torsion and deliver performance and reliability at high speed. The efficient 5-bar reel is fitted with 85 heavy-duty double steel coil tines to assure clean crop pickup and throughput. “S”-shaped side sheets ensure that crop flows smoothly and evenly into the baler, while the full-width-powered, feed-assist roller delivers high-capacity feeding into the feed channel in even the bulkiest crop material.

OUTSTANDING PICKUP VISIBILITY
The baler’s short and narrow drawbar and non-reflective yellow color provide excellent visibility of the pickup while baling.

BENEFITS OF SHORTER PARTICLE LENGTH
Cutting crop as it’s fed into the baler delivers shorter particle lengths, which results in tighter material packing and greater bale density. Cutting material with up to 29 spring-protected knives can help improve silage bale fermentation, feed digestibility, bale breakup and mixing, and material absorbency. Added density can also mean more weight per bale and more tons per truck, providing even greater savings.

KNIFE DRAWER
Sharp knives require less power and lead to a more consistent cut length. The one-piece, slide-out knife drawer makes knife inspection and sharpening fast and easy. Knives are hydraulically activated from the cab. When cutting is not desired, the knife slots are easy to keep clean by using the supplied blanking plates that are conveniently stowed.

DIRECT PRECOMPRESSION CHAMBER FEEDING
The high-performance CropCutter® rotor cutting and feeding system moves material directly into the pre-compression chamber. When the desired pre-chamber density is achieved, the stuffer starts and swiftly moves the perfect flake into position. In the most difficult baling conditions, the rotor floor can hydraulically drop away to release the crop pressure for even easier restarting.

RELIABLE PACKER FEEDING
The high-capacity packer model features three, three-tine packer forks made of Hardox®-brand steel that deliver performance, durability, and wear resistance. To match the baler's high throughput, the packer driveline is upgraded to handle up to 25% more power than BigBaler PLUS models.

INDUSTRY-LEADING PRECOMPRESSION TECHNOLOGY
The packer feeder, precompression chamber and stuffer system provide unmatched reliability and consistent bale formation. Holding fingers retain crop until the desired density is achieved, and then paddles at the bottom of the chamber trip to start the stuffer motion. The heavy-duty shuttle feeder swiftly moves even the heaviest crop into the chamber, resulting in filled corners for perfectly square bales.

HIGH-DENSITY PERFORMANCE
The BigBaler 340 High Density can deliver up to 22% higher-density bales than other conventional large square balers, and up to 15% more when compared to the BigBaler 340 PLUS.

POWERFUL PLUNGER
The plunger plays a critical role in bale density, which is why the BigBaler 340 High Density has an improved plunger design. This plunger provides impressive results, delivering a 29.5-inch (748-mm) stroke, 48 times per minute, with extreme plunger force that is 58% greater than BigBaler 340 PLUS models for even denser bales.

PRECOMPRESSION FOR UNIFORM BALE SLICES
The BigBaler 340 High Density benefits from adjustable precompression chamber technology developed for high-density baling. Crop is fed into the chamber and held there until it reaches the correct density. Improvements have been made to the control fingers – including their construction and motion – to deliver even more consistency and higher density.

STRONG DENSITY RING
The real technological revolution that delivers industry-leading density for the BigBaler 340 High Density is the rear-mounted density ring. The unique design features three, double-acting, top-mounted cylinders and two double-acting cylinders on each side to create a pressure ring that opens and closes the density doors with precision. This system also features rapid door closing, which means you can get back to baling even quicker.

BETTER CONTROL WITH A LONG BALE CHAMBER
To deliver consistent productivity regarding density and bale shape over the entire baling day, the bale chamber is over 13 feet, 3 inches long – the longest in the industry. Even on the hottest day, dry and slick crops are no problem for the BigBaler 340 High Density’s bale chamber.

HEAVY-DUTY FRAME
A new, even more robust frame has been designed to withstand higher-density loads created by the baler. The new main gearbox is mounted to the top beam to reduce crop accumulation underneath and increase durability. Additionally, the drawbar is not part of the main frame to facilitate height adjustment via the dedicated height adjustment rods, which is convenient when baling with different tractors.

EFFICIENT SUSPENSION
The new hydraulic suspension system delivers improved ground following and ensures perfect weight distribution across all four wheels. On uneven terrain, when the front wheel goes up, the rear wheel goes down, which improves field-hugging performance and reduces tire wear.

AUTO-STEER TANDEM AXLES
The Auto-Steer tandem axle provides efficient turning and less stubble damage. The baler’s wheelbase has also been extended to deliver a best-in-class steering angle for even tighter turns, resulting in shorter headlands, easy road transport, and improved servicing access.

LARGER TIRES
Larger diameter tires, up to 59 inches tall, can be fitted to the BigBaler 340 High Density to help reduce soil compaction. Choose the standard 600/50 R22.5 tires, or upgrade to the 620/55 R26.5 tires for the lightest possible footprint. Regardless of tire choice, transport width remains less than ten-feet wide down the road.

START WITH THE PLUNGER BACK
High density does not mean hard starting. When the machine is stopped, the smart brake stops the plunger away from the bale face. Since the plunger does not press on the bale face at startup, initial harsh-starting torque loads are virtually eliminated.

SMARTSHIFT™ GEARBOX
The award-winning SmartShift gearbox features two-speed startup technology to deliver even smoother baler engagement, so your tractor’s driveline is always protected. How does it work? Once the PTO reaches 850 rpm, the easy-start feature engages the baler and automatically shifts from 1st to 2nd gear, accelerating the flywheel to a maximum speed of 1440 rpm at full PTO speed.

HIGH-ENERGY FLYWHEEL
BigBaler 340 High Density balers feature a flywheel that is 130-pounds heavier than the one found on BigBaler PLUS balers. It also has a 16% larger diameter, coming in at 42.5 inches (1080 mm), and turns faster to deliver 230% more energy.

BUILT FOR LONG LIFE AND DURABILITY
The new super-duty main gearbox has two drive gears driving the main output gear, which leads to an increased gear-to-gear surface contact area for greater durability and more efficient, balanced power load distribution.

STRONGER KNOTS AND FEWER BROKEN BALES
Delivering up to a 26% increase in overall tensile strength for reduced breakages, the Loop Master™ double knotting system forms the first knot in each bale with a loop style, which is 37% stronger compared to a standard or conventional large square baler knot. Perhaps more importantly, this knotting system eliminates twine offcuts, resulting in cleaner fields and feed – a great advantage for export hay producers. This system saves nearly four miles of twine for every 10,000 bales.

KNOTTER SHIELDING
Shielding around the knotter helps to keep the system free of chaff. To design this shielding, New Holland used advanced fluid dynamics to analyze air flow and eliminate dead spots of air that could lead to debris build-up. The result? BigBaler High Density balers tie bales flawlessly in even the dustiest crops.  

Three electric fans are standard, and the flywheel’s webbing is fan-blade-shaped to keep air moving and the entire baler cleaner and cooler.  

An optional compressed blowoff kit is available for working in the harshest conditions. The system's 21 nozzles are positioned to help keep the knotting system even cleaner when baling.

IMMEDIATE MISS-TIE ALERT
Individual miss-tie flags and electronic miss-tie sensors are standard equipment to identify the individual knotter that miss-tied. When a bale is tied incorrectly, the monitor alerts the operator with an audible alarm and a symbol on the monitor.

PRECISION SOLUTIONS THAT ENHANCE YOUR PRODUCTIVITY
During long baling days, small things can make a big difference. The suite of precision features available for the BigBaler High Density Series are designed to remove limiting factors in the efficiency and productivity of your baling operation. From industry-leading IntelliSense™ baler automation for hands-free baling to streamlined data collection, a host of features helps you maximize your efficiency.

INTELLICRUISE™ AUTOMATION
Increase overall capacity and productivity while baling with the IntelliCruise™ feed rate control system. IntelliCruise automatically matches your tractor’s forward speed to crop load to maintain a constant feed rate while baling, enhancing productivity and greatly reducing operator fatigue.

Tailor the IntelliCruise system to fit your goals with two modes. Charge Control Mode automatically adjusts the tractor’s speed to meet optimum capacity. IntelliCruise automation measures the throughput of crop yield fed into the pre-charge chamber and the time needed to fill the chamber. Slice Control Mode adjusts the tractor’s speed according to bale slice thickness and creates the number of slices defined by the operator, with corresponding slice thickness based on preset bale length.

INTELLISENSE™ BALE AUTOMATION
Large square baling demands long hours of your continuous focus. You steer to follow each swath and simultaneously observe swath density and crop flow to prevent overloads while adjusting your tractor’s speed to match. You monitor bale fill indicators and steer your tractor accordingly, while also monitoring bale slice numbers and weights. By proactively automating tractor steering by combining SmartSteer™ swath guidance and the IntelliCruise™ feed rate control system, award-winning IntelliSense™ bale automation features a LiDAR (light detection and ranging) sensor that can relieve you of these tasks, day or night. The result? Hands-free baling to help reduce fatigue, less risk of downtime from crop plugs, and greater bale uniformity and consistency due to automated filling, and less fuel consumption.

Available on:

All BigBaler High Density models (since 2020)
Compatible with all New Holland T7 LWB, T7 HD and T8 Auto Command™ tractors (equipped with Class 3 ISOBUS unlocked for steering and speed control)

SMARTFILL™ II SYSTEM
To ensure uniform, consistently good-looking bales, the SmartFill II system uses calibrated load cell sensors on the plunger to ensure uniform left and right fill. The system also indicates if the position of the baler needs to be adjusted in relation to the swath.

ELECTRONIC BALE LENGTH
For the highest level of precision, bale length is controlled from the tractor cab on every BigBaler. Simply set the length (118 inches maximum) and go. “Smart” star wheels track the actual length of the bale and trigger the knotters at exactly the right time. When a field or job is finished, tying of an unfinished bale is done safely from the cab. The standard Bale-Eject™ feature allows you to choose partial or full bale ejection to clear the chamber before moving on.

PRECISION MOISTURE SENSING
The BigBaler 340 High Density moisture sensor options displayed on the IntelliView™ monitor allow you to make on-the-go baling decisions when crop isn’t ready. The two-star wheels penetrate the bale and pass an electric current between the two elements to determine the exact moisture of the bale. This moisture sensing option is expandable to New Holland CropSaver™ hay preservative. When conditions call for closely monitoring bale moisture without the use of preservatives, such as when baling straw, the rub-pad moisture sensors provide an accurate bale moisture.

CROP RFV™ SYSTEM
During baling, the Crop RFV system option measures the weight of the bale and moisture content based on the leaf-to-stem ratio to calculate your Relative Feed Value (RFV), or the nutritional value of the bale. The Crop RFV system requires the ActiveWeigh™ on-the-go bale weight system and a precision farming moisture sensor option. You can also pair the CropID™ system or a dye marker kit to easily identify bales within a specific RVF range to make feeding even easier. Contact your local New Holland dealer for complete compatibility details.

CROPSAVER™ PRESERVATIVE
When you treat hay with New Holland CropSaver hay preservative, you can bale at moistures up to 30% without worrying about heating or mold damage. This means you can start baling earlier and stay in the field later to finish on your schedule, no matter the weather conditions. CropSaver preservative also helps to maintain both the fresh smell and green color of hay, even after it's stored. Choose an electronic applicator control system to set and maintain a constant application rate, or an optional automatic control system that accurately senses moisture on the go and adjusts the application of preservative every three seconds to match the condition of the hay.

ACCURATE ON-THE-GO BALE WEIGHING
The multi-award-winning ActiveWeigh™ on-the-go bale weight system boasts industry-leading accuracy of +/- 2%. It is integrated with the soft drop two-piece roller bale chute and measures the weight of the bale at the exact moment it balances on the rear of the roller chute prior to tipping off onto the ground.

SPEND MORE TIME BALING AND LESS TIME SERVICING
The BigBaler 340 High Density Series has been designed with easy maintenance in mind – after all, you want to spend more time baling and less time maintaining the baler. Efficient features include fewer daily grease points, shields that open wide, and easy access to the underside of the baler. The large, flat, upper service deck provides convenient access to the Loop Master™ knotter system. The body of the baler includes a larger platform for easier and safer servicing. Folding safety railings provide a low height for transport and better access to the front of knotter fans.

WIDE-OPEN SERVICING
For easy servicing, a single-piece, two-stage front hood easily glides open on gas struts. The shield opens partially for fast access to all service points, or fully for complete access to all areas for cleaning.

AUTOMATIC OILING AND GREASING
To reduce maintenance and enhance reliability, automatic oiling and centralized greasing systems are standard to keep all chains oiled and major grease points lubricated, including the plunger bearings and knotters.

EASIER TWINE LOADING AND THREADING
For easy twine loading and threading, the baler’s hydraulic axles can be lowered to bring the twine boxes closer to the ground. Even better, the entire twine box unit has been fitted with hydraulics that allow it to swing out fully to make cleaning even easier and provide greater access to the baler’s inner workings. The twine boxes support 36 XL spools of twine that can be connected simultaneously.

SUPERIOR DAY AND NIGHT VISIBILITY
Yellow paint is applied to the baler’s frame to improve visibility and safety during servicing. At nighttime, when you partner a BigBaler 340 High Density with a New Holland high-horsepower tractor, you can get 360° LED lighting to maintain your productivity, safety, visibility, and ease of operation. Standard ultra-bright LED strips have been strategically placed on the baler to increase visibility to the MaxiSweep pickup and Loop Master™ knotting system. An optional service light package includes additional LED lighting for both twine box doors and the right- and left-hand side of the stuffer mechanism, so nighttime servicing is easier.
